ABSTRACT
Demography and population genetics, though they have emerged as separate disciplines, tried to explain the population structure in each own way. Here in this article, the interrelationship between these disciplines are reviewed with reference to the population structure. The correlation and interdisciplinary between these two disciplines in explaining the population can be discussed under three different approaches i.e. demography, evolutionary and epidemiology. Both the demographic and evolutionary parameters are interrelated. The demographic parameters are influenced by genetic factors and in return the evolutionary fate of a population is explained through demographic parameters – fertility and mortality. This correlation is more evident in epidemiological approach. Nowadays with the rise of complex disorders among the interbred populations, the complete understanding of the population structure is much needed.
